Final answer:
Packet fragmentation is a process used in networking to break up large packets into smaller fragments for transmission.
Step-by-step explanation:
Packet fragmentation is a process used in networking to break up large packets into smaller fragments that can be transmitted over a network.
In the case of an IPv4 packet that is 9000 bytes, it will be fragmented into 2 packets. The first fragment will be 1480 bytes and the second fragment will be 7520 bytes.
The maximum size of an IPv4 packet is 65535 bytes, but it is common for networks to have a maximum transmission unit (MTU) size of 1500 bytes. Therefore, when a packet exceeds the MTU size, it needs to be fragmented into smaller packets for transmission.
